Vitamin A and D have showed unexpected and crucial effects on immune system. Vitamin A includes innate immune towards microbial infection, absence of vitamin A can increase the chance of bacterial, viral, and parasitic infection. Also excessive intake of vitamin A Is associated with toxicity, including blocked hematopoiesis, mitogen-induced T-cell spread, antigen-specific antibody production, and an increased susceptibility to infectious organisms. Vitamin A is also given by Retinoid supplement to treat the skin effects of T-cell lymphoma. Vitamin C also known as Ascorbic Acid also contribute in innate immunity system, Vitamin C works during infection to prevent oxidative damage. Lower concentration of vitamin C in leukocyte is related to reduce immune response in humans. It has been proven that Vitamin C concentrations in the plasma and leukocytes rapidly decline during infections and stress. Iron chelators such as desferrioxamine inhibit the activity of phagocyte oxidase and reduce reactive oxygen intermediate-dependent killing of bacterial pathogens, both in vitro and in vivo. Lastly, Zinc is a dietary trace mineral that is responsible for growth and development, and it is essential for the function of cells of the immune system. It increased susceptibility to

Main compounds of the enzymatic antioxidant system are three, namely, SOD, CAT and tT which have an important role in detoxifying of H2O2 and superoxide anion in cells. Ample of hepatotoxic drugs induces the liver damage by lipid peroxidation indirectly or directly. The proxy radicals are main factors that mediate lipid peroxidation leading to liver injury and kidney damage(41). MDA as a main reactive aldehyde appears during polyunsaturated fatty acid peroxidation in the biological

When we’re young, our cells have a very strong defense system known as superoxide dismutase (SOD) that kicks free radical butt. But as we get older, SOD doesn’t work as well. Without SOD keeping the peace, the free radicals have a field day and wreak as much damage as they possibly can causing our cells, and eventually us, to die. Free radicals have also been linked to a number of diseases such as cancer, dementia and heart disease.

Did you know that diets rich in anti-oxidants have been shown to prevent disease, inflammation and improve immune systems in studies dating back to the 1960’s!

These superoxides may be dangerous because they alter the structure of iron and protein via reduction. They may also undergo dismutation to form hydrogen peroxide which, in turn, gives rise to hydroxyl radicals, the most reactive ROS (Gulumian and Van Wyk, 1987; Agarwal et al., 2005). Hydrogen peroxide is not a free radical but its neutral charge allows it to pass through cell membranes and so this makes it very dangerous (Kurutas, 2015). Other internal or endogenous sources for these free radicals are inflammation, xanthine oxidase, peroxisomes, phagocytosis, exercise and ischaemia. Exogenous factors which lead to the development of these ROS include smoking, ozone, environmental pollutants, radiation, pesticides and drugs (Lobo et al.,

Licorice root is used worldwide as a natural sweetener, as well as a flavoring agent. The main composition of plant Flavonoids and Isoflavonoids act as inhibition platelet aggregation, and anticancer, antioxidant (20). Aly et al.,2005(21) indicate that liqurice have potent anti-inflammatory reduction edema about 78.3 while diclofen about 73.9% also have anti-ulcerogenic activity associated with a reduced acid output and an increased mucin secretion, an increase in prostaglandin E2 release and a decrease in leukotrienes (22). Many volatile oil and vitamins such as B1,B2,B3,B6,C,E, Biotin, Foli acid, Pantothenic acid act as expectorant, laxative, liquiritin act as antitussive (23). Also contain Coumarins Herniarin and umbelliferone (24).moreover plant used for treatment of asthma , chronic fatigue, hormonal disturbance , antiviral, antibacterial , hepatoprotective, anti-oxidant , antiulcer, ant mutagenic, Hypothermic antioxidant, anti-inflammatory, relieve pain , expectorant, hypoglycemia,

Your body is in a constant battle against infection, diseases and the formation of free radicals. However, there's a secret weapon that can help you fight against these things: antioxidants! Antioxidants are elements such as vitamins A, C and E that counteract the damage caused by free radicals and help protect your healthy cells. Free radicals are the molecules that contain unpaired electrons, which make them highly reactive. In this form, they can cause damage by attacking healthy cells, and when these cells grow weakened, you become more vulnerable to disease.

The roles of antioxidants( Endogenous compounds) are to neutralize the excess of free radicals, to protect the cells against their toxic effects and to contribute in disease

vulgare shown to have significant antibacterial activity in vitro as compared to some standard antibiotics[53]. Butanol and aqueous fractions of F. vulgare fruit showed intermediate free radical scavenging activity in vitro[54]. A group of rat pretreated with aqueous extract of F. vul-gare shown to have suppressed ethanol-induced gastric lesions. Also, this extract significantly reduced lipid peroxidation and increased antioxidant activity[70]. Administration of methanolic extract of F. vulgare fruit orally to mice has been shown to suppress Type 4 allergic reactions as well as acute and subacute inflammatory responses and also shown moderate centeral analgesic effect. In addition, it significantly enhance plasma antioxidant status while suppressing lipid peroxidation chain

The second series of experiments examined sensitization by determining both the time of onset of sensitization, as well as, the magnitude of sensitization when intensity of stimuli is manipulated. To do so, experimenters utilized the same experimental design as that of the dishabituation experiment; however, the animals were presented two baseline stimuli at equal intervals before tail stimulus and then an additional

The enhancing influence of OLE may possibly be associated to its multifunctional radical scavenging and anti-inflammatory

Natural Antioxidants are abundant in fruits and vegetables such as, apples, blueberries, broccoli, cherries, cranberries, Grapes, spinach, and Spirulina a blue-green algae.

Gooseberry’s rich nutrient content helps in the prevention DNA cell damage induced by free radicals.

Abstract: In this lab report two unknown substances will be tested. The tests performed were looking for the presence of the main biomolecules, Carbohydrates, Lipids, and Proteins. The tests used will be used in the Lab report are; The Benedicts test to test for sugars, the Iodine test for coiled or non-coiled carbs, The Grease-spot test for lipids, and the Biuret test for proteins. Tests show that both substances had different responses to the Benedicts test. Both substances shared the same response to the Iodine test. In the Grease-spot test both showed the same. In the Biuret test the unknown substances resulted differently from each other.

Chocolate has two groups of antioxidants called flavonoids and polyphenols. Antioxidants fight against free radicals in the body. Free radicals are unbalanced compounds created by the natural cellular processes in the body and from environmental toxins. Antioxidants are compounds including vitamins, minerals and phytochemicals that neutralize free radicals and protect the body from their damage. The substances in antioxidants counteract with the damaging normal effects of the body’s process of oxidization. Research shows that antioxidants help in preventing the development of chronic diseases such as cancer, heart disease, stroke, Alzheimer’s, rheumatoid arthritis, and cataracts.
